relay bit for a safe connection to other systems.
With this relay bit, built on the HDK perf board W29 with just a few extra standard available electronic components, a safe connection to other electronic systems can be made. The separation is realized via a miniature relay, controlled by any input bit. The external system can be connected to the relay contacts via the isolated terminals on the bit surface. These contacts are fully separated from the LittleBits system.
Now all the LittleBits configurations and automated designs can be used in combination with existing electronic products, for example:
Miniature motors (ON/OFF and reverse direction)
Any other system you can think of..
Although the relay contacts can withstand more, it is strongly advised for safety reasons to use this bit only for systems up to a maximum voltage of 12 V with a maximum current load of 1 Amp.
